<p class="MsoNormal">Hello Richard, <o:p></o:p></p>
<p class="MsoNormal">We often build different boat designs for different processes, so that its obvious what boat goes with what process. Shell and rail boats can achieve the same process results, but appear completely different.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It is more difficult to do this with automated boat loading mass transfer tools, but for hand loaded its relatively easy.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We also do this from time to time with silicon carbide paddles, 2 inch square handle for oxide, and1.75 or 1.25 square for anneal.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Scribe is fine, but the boats (any quartz) should be annealed at 1175 for 8 hours to relieve the stress. The anneal is part of the process when we manufacture boats with the various suppliers.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am glad to review boats and quartz offline. <o:p></o:p></p>

<p class="MsoNormal">HI Everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are having an issue controlling the quartz boats for our furnace operations. We use 4” and 6” boats with 2 different slot widths. DO you think we could lightly scribe a tube number and size on the rail of the boat? I am concerned that
it would crack.<o:p></o:p></p>
